Hi @rianboy18 unfortunately CTGAN does indeed not work with null values.
Maybe this will change in the future, but for now it is intended to work only with single tables of numerical or categorical data, with no nulls.

If you want support for more complex scenarios, like nullable, boolean or datetime columns, or multi-table datasets, please have a look at the SDV project.

Also note that, even though CTGAN is not yet available as an SDV model, work is currently being done in order to support it as well as other DL based synthesizers.
